Definitions
- the field of the present invention relates generally to condoms, and more specifically to condoms having a lubricant system which includes a genital desensitizing agent and controls the application thereof to male genitalia.
- compositions containing a male desensitization agent suitable for preventing premature ejaculation Many of these compositions provide a water-based lubricant with benzocaine as the active component at a concentration of from about 3% to 7.5%. Such compositions are inconvenient to use, in that they require direct application to the male genitalia prior to intercourse. In addition, these compositions typically expose the female partner to the composition and its desensitizing effects with such exposure being highly undesirable.
- Heidenfelder U.S. Pat. No. 4,840,188 discloses the coating of the interior surface of a condom with a local anesthetic such as benzocaine to provide desensitization.
- a local anesthetic such as benzocaine
- the location of the desensitizing agent on the interior surface of the condom provides advantages over direct application products.
- the present invention generally provides a condom that incorporates two distinct lubricating compositions.
- One such composition is a relatively high viscosity lubricant composition containing at least one desensitizing agent that is bottom shot into the interior of a nipple up condom to coat the interior surfaces thereof.
- a second, lower viscosity lubricant composition containing no desensitizing agent is top shot on the outside of the condom prior to, or at the same time as following the application of the bottom shot lubricant composition.
- the high viscosity lubricant composition with a desensitizing agent remains substantially in place during packing, shipping, storage, and use so that the full benefits of continuous contact with the desensitizing agent can be realized. In this manner, separation of the first lubricant composition containing the desensitizing agent from the exterior surfaces of the condom is maximized in order to minimize contact with the female partner and thereby avoid desensitization of the female genitalia.
- a condom comprising:
- a male genital engaging tubular sheath having an inner surface and an outer surface
- a first lubricant composition comprising an effective amount of a male genital desensitizing agent located on at least a portion of the interior surface of the tubular sheath, said first lubricant composition having a relatively high viscosity sufficient to maintain the first lubricant composition on the inner surface of the condom during packaging, shipping, storage, and use; and
- a second lubricant composition containing no desensitizing agent and having a lower viscosity than the first lubricant composition, the second lubricant composition being located on the outside surface of the tubular sheath.
- the first lubricant composition has a viscosity of from about 10,000 to 75,000 cps, while the second lubricant composition has a viscosity of from about 500 to 20,000 cps.

Abstract
Description
- This Application is related to co-pending Provisional Application Ser. No. 60/251,486 filed Dec. 5, 2000, for “Condom With Male Genital Desensitizer Lubricant”, and takes priority therefrom. The related Application is owned by the same Assignee herewith.
- The field of the present invention relates generally to condoms, and more specifically to condoms having a lubricant system which includes a genital desensitizing agent and controls the application thereof to male genitalia.
- Much effort has been made to provide a composition containing a male desensitization agent suitable for preventing premature ejaculation. Many of these compositions provide a water-based lubricant with benzocaine as the active component at a concentration of from about 3% to 7.5%. Such compositions are inconvenient to use, in that they require direct application to the male genitalia prior to intercourse. In addition, these compositions typically expose the female partner to the composition and its desensitizing effects with such exposure being highly undesirable.
- Heidenfelder, (U.S. Pat. No. 4,840,188) discloses the coating of the interior surface of a condom with a local anesthetic such as benzocaine to provide desensitization. The location of the desensitizing agent on the interior surface of the condom provides advantages over direct application products.
- Despite these efforts, there is still a need to provide a condom with desensitizing capability that can be readily employed without risk of exposure to the female partner and still provide the benefits of a lubricating composition.
- The present invention generally provides a condom that incorporates two distinct lubricating compositions. One such composition is a relatively high viscosity lubricant composition containing at least one desensitizing agent that is bottom shot into the interior of a nipple up condom to coat the interior surfaces thereof. A second, lower viscosity lubricant composition containing no desensitizing agent is top shot on the outside of the condom prior to, or at the same time as following the application of the bottom shot lubricant composition. The high viscosity lubricant composition with a desensitizing agent remains substantially in place during packing, shipping, storage, and use so that the full benefits of continuous contact with the desensitizing agent can be realized. In this manner, separation of the first lubricant composition containing the desensitizing agent from the exterior surfaces of the condom is maximized in order to minimize contact with the female partner and thereby avoid desensitization of the female genitalia.
- In one aspect of the present invention there is provided a condom comprising:
- a male genital engaging tubular sheath having an inner surface and an outer surface;
- a first lubricant composition comprising an effective amount of a male genital desensitizing agent located on at least a portion of the interior surface of the tubular sheath, said first lubricant composition having a relatively high viscosity sufficient to maintain the first lubricant composition on the inner surface of the condom during packaging, shipping, storage, and use; and
- a second lubricant composition containing no desensitizing agent and having a lower viscosity than the first lubricant composition, the second lubricant composition being located on the outside surface of the tubular sheath.
- In a preferred form of the invention, the first lubricant composition has a viscosity of from about 10,000 to 75,000 cps, while the second lubricant composition has a viscosity of from about 500 to 20,000 cps.
- Various embodiments of the present invention are described below with reference to the drawings, in which like items are identified by the same reference designation, wherein:
- FIG. 1 is a schematic diagram showing a method of applying the first lubricant composition to the interior portion of a condom and the second lubricant composition to the exterior portion of the condom for one embodiment of the invention;
- FIG. 2 is a view similar to FIG. 1, the difference being that the condoms are shown in cross section taken along line2-2 of FIG. 1;
- FIGS. 3 through 10 are respective side views of various examples of condoms that can be prepared in accordance with the present invention; and
- FIG. 11 shows a block diagram of processing equipment for making the first and second lubricant compositions for use in the present invention.
- In one embodiment of the present invention, the interior surface of a condom is lubricated with a first lubricant composition containing a relatively high viscosity lubricant along with at least one male genital desensitizing agent.
- As used herein the term “desensitizing agent” means any material including topical anesthetics that reduce the sensitivity of male genitalia in a manner which may prevent premature ejaculation. Examples of suitable desensitizing agents include benzocaine, butambin picrate, dibucaine, dibucaine hydrochloride, dimethisoquin hydrochloride, dyclonine hydrochloride, lidocaine, lidocaine hydrochloride, pramoxine hydrochloride, tetracaine, tetracaine hydrochloride, benzyl alcohol, camphor camphorated metacresol, juniper tar, menthol, phenol, phenolate sodium, resorcinol, diphenhydramine hydrochloride, tripelennamine hydrochloride, and combinations thereof. The preferred desensitizing agent is benzocaine.
- The desensitizing agent may be present in the first lubricating composition in a desensitizing effective amount which may be typically from about 0.5 to 25% by weight based on the total weight of the of the composition, preferably from about 3 to 7.5% by weight. In a preferred composition the desensitizing agent is benzocaine in an amount of about 6.0% by weight. It will be understood that the selection of an effective amount of the desensitizing agent is within the skill of the art and will depend in part on the particular desensitizing agent chosen and the type of other components of the first lubricating composition.
- The type of lubricants which may be used in the first lubricant composition are selected to provide a relatively high viscosity to the composition. The viscosity should be sufficient to enable the first lubricant composition to be applied to the inner surface of the condom and retained thereon during packaging, shipping, storage, and use without splashing and/or splattering.
- The first lubricant composition will typically have a viscosity of from about 10,000 to 75,000 cps at ambient temperatures, preferably from about 10,000 to 25,000 cps. In addition, it is desirable that the lubricant be able to solubilize the desensitizing agent to provide uniform distribution of the same over the inner surface of the condom. Typically, lubricants which may be effectively employed in the first lubricating composition could include but are not limited to glycols (e.g. polyethylene glycols, propylene glycol), water-based gels (e.g. glyceryl polymethacrylate, carboxymethyl cellulose), silicone-based oil and gels, mineral oils, and so forth.
- The second lubricating composition which is applied only to the exterior surface of the condom, does not contain a desensitizing agent. The viscosity of the second lubricating composition is lower than the first lubricating composition and allows the lubricant to be easily spread around the rolled condom to lubricate the outer surface thereof.
- The viscosity of the second lubricant is typically in the range of from about 500 to 20,000 cps. The selection of a suitable lubricant will depend on the type of condom material.
- Typical lubricants used for the second lubricating composition include, but are not limited to, the same lubricants used for the first lubricating composition but with a lower viscosity.
- The first and second lubricating compositions may be employed on condoms having a variety of shapes and/or compositions. Typical condom forming materials include natural rubber latex, synthetic elastomers such as polyurethane and the like., and natural skin, such as a lamb secum. Various shapes of condoms employed in the present invention are exemplified by reference to FIGS.3-10 as hereinafter described.
- A method of applying the first and second lubricant compositions to a condom will now be described with reference to FIGS. 1 and 2. In one embodiment of the invention, a commercial packaging machine provides an indexed motion in the direction of the arrow1, for moving rolled
condoms 3 in the direction shown. However, in a preferred second embodiment, the motion is not indexed, but rather is timed through the use of rotating cams to activate pumps (not shown) at appropriate times for ejecting associated lubricants fromnozzles condoms 3, whereas indexing employs non-continuous movement. The rolledcondom 3 with itsnipple 5 up first passes beneath avertical nozzle 7 for applying a relatively low viscosity secondlubricating composition 8 on the exterior surfaces of the condom onto and proximate thenipple 5. Thecondom 3 moves to a position over anothernozzle 9 used to apply a first lubricatingcomposition 11 containing a male genital desensitizing agent to the interior or inside surfaces of thecondom 3 typically proximate the closed end thereof. Thecondom 3 which has been provided with the second lubricant composition on the exterior surface of the condom is moved over thelower nozzle 9. After thenozzle 9 is used to apply the first lubricatingcomposition 11 containing a desensitizing agent to the interior surface of the nipple and adjacent areas, the completelylubricated condom 3 then is encapsulated between the twofoil layers nozzles lubricants nozzles lubricants - As previously described, the
condoms 3 of the present invention can have any desired shape. Representative examples of various shapes and sizes ofsuitable condoms 3 are shown in FIGS. 3 through 10. The length of thecondoms 3 typically can range from about 160 mm to 220 mm. The nominal length of the condom is typically about 180 mm, with the condom also having a lay-flat width of about 52 mm. - As shown specifically in FIG. 3 the
condoms 3 may have parallel walls with a nipple at the closed end, or as shown in FIG. 4 parallel walls without a nipple. Thenipple 5 may or may not be included at the closed end. In FIG. 5, thecondom 3 has a shape approximating that of a baseball bat. In FIG. 6, thecondom 3 includes a taperedportion 17 in its otherwise parallel sidewalls. In FIGS. 7 and 8 thecondoms 3 include bulbouslowermost portions 19, with the condom of FIG. 7 also includingcircular texturing 21 and raisednib portions 23. The configuration of thecondom 3 as shown in FIG. 9 includes texturing in the form ofspiral ribs 25, along with raisednibs 23. The configuration of the FIG. 10 includes raised successivecircular ribs 27. All of the condoms of FIGS. 3-10 and those not specifically disclosed may be treated with the lubricating/desensitizing system of the present invention. - A first lubricant composition in accordance with the present invention having the formula shown in Table1 was prepared as follows:
TABLE 1 Ingredient Percent w/w Propylene Glycol 44.0% w/w. Polyethylene Glycol 400 15.0% w/w. Lubrajel ® CG* 35.0% w/w Benzocaine USP 6.0% w/w 100.0% - A method for manufacturing the first lubricating composition shown in Table 1 is now be described, with reference to FIG. 11. A hemispherical jacketed
kettle 31, is provided with heating and cooling equipment. The kettle is equipped with a variable speed counter current sweep scraper, and a variable speed air mixer with propellers, as known in the art, to provide proper agitation. Three pumps, represented bynumerals 33 through 35, are used to charge thekettle 31 with the particular components of the composition shown in Table 1. A Graco FT-14pump 33 is preferably used to pump the lubricant Lubrajel® CG product into thekettle 31. In certain applications only asingle pump 33 may be required due to the very high viscosity of the Lubrajel® CG. Once the first lubricating composition is formed, a 100 mesh SS Triclover type strainer is used to provide afilter 36 for filtering the first lubricating composition prior to placing the same into astorage container 37. Typically, thestorage container 37 is provided by a plurality of storage drums constructed of stainless steel, or high density polyethylene, or poly-lined fiber drum. - For the preparation of a batch of about 1,400 kg (kilograms) of the first lubricating composition shown in Table 1, the pumps33-35 are operated to discharge 616 kg of propylene glycol, 210 kg of polyethylene glycol, and 490 kg of Lubrajel® CG into a 400
gallon capacity kettle 31 from a storage container (not shown), respectively under stirring with a variable speed counter current sweep scraper, and variable speed airmixer with propellers. The contents of the kettle are heated to between 75° C. and 80° C. During heating the air mixer is increased in speed to break up gel bodies and the kettle is charged with 84.0 kg of benzocaine. While maintaining the temperature of the contents of the kettle between 75° C. to 80° C., the mixture is stirred until the gel bodies have dissipated, typically from two to four hours. When the gel bodies have dissipated, the speed of the agitation equipment is decreased, while mixing is continued for a minimum of four hours at a temperature of 75° C. to 80° C. 20 After mixing as described above, the batch is cooled to between 65° C. and 70° C. When the batch is cooled, it is then discharged from thekettle 31 through thefilter 36 into storage drums 37. The viscosity of the thus produced first lubricating composition is in the range of from about 10,000 to 75,000 cps which may be adjusted by altering the amount of the respective starting materials. -
